<p>Internal links are one of the easiest ways to improve your SEO and reduce bounce rate. But manually writing contextual sentences around each link is tedious — and just dropping a link on a keyword looks unnatural.</p>
<p><strong>Purrlink solves this.</strong> It uses AI to generate a “bridge sentence” that naturally introduces your internal link, so it reads like part of your content — not an afterthought.</p>
<p><strong>Before:</strong></p>
<blockquote>
<p>“Taking care of [cats] requires attention…”</p>
</blockquote>
<p><strong>After:</strong></p>
<blockquote>
<p>“Taking care of cats requires attention. If you’re just starting out, check out our <strong>[Beginner’s Guide to Cat Care]</strong> for helpful tips.”</p>
</blockquote>
<h4>Why Purrlink?</h4>
<ul>
<li><strong>Better for SEO</strong> — Contextual internal links help search engines understand your site structure and pass link equity between pages</li>
<li><strong>Better for readers</strong> — Bridge sentences guide visitors to related content naturally, increasing pageviews and time on site</li>
<li><strong>Saves time</strong> — What takes minutes to write manually, Purrlink generates in seconds</li>

<h3>External Services</h3>
<p>This plugin connects to the <strong>Google Gemini API</strong> to generate bridge sentences using AI.</p>
<p>When you click “Generate” in the Purrlink sidebar, the following data is sent to Google’s servers:</p>
<ul>
<li>The text you selected in the editor (source context)</li>

<li>Your website profile settings (website name, niche, target audience, brand voice)</li>
<li>Your persona settings (tone, writing style, language notes)</li>
</ul>
<p>No data is sent automatically — it only happens when you explicitly click “Generate” or “Regenerate”.</p>

<p>The “LuckyWP Wiki Linking” plugin allows to easily organize a linking in the wiki style on the website: you specify the keyword phrases for a post, and the plugin places links to this post on other website pages that have the keyword phrases are present in the text.</p>
<span class="embed-youtube" style="text-align:center; display: block;"><iframe loading="lazy" class="youtube-player" width="750" height="422" src="https://www.youtube.com/embed/jwClpVEN6hs?version=3&rel=1&showsearch=0&showinfo=1&iv_load_policy=1&fs=1&hl=en-US&autohide=2&wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox"></iframe></span>
<p>You DON’T NEED to manually place each individual link, the plugin will make it for you.</p>
<p>When placing a link in a post, whole words are only taken into account. For example, the link with the keyword phrase bus will be added to the text:</p>
<blockquote>
<p>She got on the <strong>bus</strong> at Clark Street.</p>
</blockquote>
<p>… and the link will NOT be added to the text:</p>
<blockquote>
<p>I’m here on business.</p>
</blockquote>
<p>In addition to links to the posts of the website, you can also place custom external links by specifying them when adding a keyword phrase.</p>

<li>When creating/changing a post we add a keyword phrase to it.</li>

<li>Profit! Links to the post are already available on other website pages.</li>
</ul>
<p>In the <a href="https://theluckywp.com/product/wiki-linking/" rel="nofollow ugc">premium version</a> the second step can be skipped — links will automatically be created!</p>
<h4>Features</h4>
<ul>
<li>Up to 30 keyword phrases for the entire website (In the <a href="https://theluckywp.com/product/wiki-linking/" rel="nofollow ugc">premium version</a> the number of keyword phrases is unlimited) and unlimited number of links to them.</li>
<li>The links is displayed ONLY on the single page of a post, in all other places (RSS feed, the editor on the control panel and etc.) this link will NOT be displayed.</li>
<li>Placing of links in the posts and the pages.</li>
<li>Placing of links in custom post types.</li>
